SAFETY-RAZOR.

Specification of Letters iatent.

Patented July 8, 1913.

Application filed July 17, 1907. Serial No. 3B4L,135.

To all whom it may concern:

Be it known that I, HAIunsoN H. Boron, a citizen of the United States,residing in the city of New York, borough of Manhattan, county and Stateof New York, have invented certain new and useful Improvements inSafetyltazors, of which the fol lowing is a full, clear, and exactspecification.

This invention relates to safety razors and has for an object to providean improved and efficient adj ust-able guard.

My improved guard is easily and quickly adjusted in respect to thecutting edge of the blade and in its preferred form atl'ords ample andsufficient support to the blade inwardly of its cutting edge, uniformlythroughout the entire length thereof.

In the drawings accompanying and forming part of this specification apracticable embodiment of a form of my invention is illustrated, it ofcourse being understood that changes of construction and details can bemade within the scope of the invention without departing therefrom.

Figure 1 illustrates a longitudinal section of the handle portion of thesafety razor and a cross or transverse section of what might be termedthe head portion. Fig. 2 is a plan view of the device illustrated inFig. 1. Fig. 3 is a plan view with the blade and backing removed. Fig. 4is a side elevation showing the parts disassembled and Fig. 5 is a sideelevation showing the parts assembled.

The razor is shown herein made up of a cap or backing 1 against whichthe 117.01 blade is hold in position by means of the guard The guard iscarried by a handle 4 which will be secured to it in some suitablemanner as'for instance by means of sol- (let. A screw threaded stud 5 iscarried by the cap or backing 1 and is engaged by a screw threadedsocket in the end of a locking member rotatably mounted in the handle 4.which is made in,the form of a sleeve. By this means the cap or backingand the guard may be moved one relative to the other. P0 sitioning pins7 are shown carried by the ea or bachng and adapted to pass throughsuitable holes in the blade and guard for positioning and holding theblade in proper position. The outer edges of the guard are shownprovided with teeth or lingers 8 50 which are located in position toengage the the guard member to thereby cause blade inwardly of itscutting edge uniformly throughout its entire length, and in conjunctionwith the cap or backing to support the blade along a longitudinal zoneinwardly of its cutting edge.

Upon the relative movement of the cap or backing 1. toward the guard thefingers 8 will be pressed into intimate engagement with the blade andupon the continuance or persistence of this movement the fingers will bespread outward thereby increasin the width of the guard relative to thead accnt cutting edge and in this manner restricting the amount of cut.Upon the reverse movement that of permitting the cap or backing to moveaway from the guard the fingers will draw inward, thereby decreasing theamount of guard and increasing the working or ellicicnt cutting ed e ofthe blade. By this means the user ot the razor may regulate the cut andby reducing the amount of exposed cutting edge or clhcient cutting edgereduce the closeness of the shave. If a closer shave however is desiredthe device will be adjusted to permit the fingers to draw inward and toexpose a wider ellicient cutting edge.

What is claimed is:

1. In a safety razor, the combination with a handle portion, a bladeretaining plate member of a yielding guard member having its toothedportion arranged at. an outward inclination relative to the plate, meansfor retaining a blade in position, and means for drawing the plate andguard toward each other to vary the angle of inclination and to therebycause the guard teeth to move outward relative to the cutting edge ofthe blade, substantially as described.

ln a safety razor, the combination with a. handle portion and a yieldingguard member of substantially bowed formation in cross section, of aplate member extending transversely of the handle portion and having anedge ad jaccnt to an outer portion of the guard member and substantiallyco-extensive therewith, means for positioning and retaining a blade withits edge adjacent the guard, and means for drawing the guard and platemember toward each other to flex the teeth to more outwardly relative tothe cutting edge of the blade, substantially as described.

33. In a safety razor, the combination with limiting or guard member toapply outwardly moving pressure to the described.

4:. In a safety razor, the combination with a handle portion, anoutwardly inclined yielding guard member having a toothed edge portionbent to move outward u on pressure being applied, of a plate mem erextending transversely of the handle portion and overlying the guardmember, means for securing the blade in position,'and eans guard teeth,substantially as for drawing the plate and guard t ward each otherwhereby the pressure is applied to the toothed edge of the guard inemberfor forcing the teeth outwardly relative to the edge of the blade.

5. In a safety razor, the combination with a handle portion, a yieldingguard member having an e teeth arranged at an outward inclination sothat when pressure is applied to the said part the teeth will be movedtransversely outward, of a plate extending transversely of the handleport-ion having its edge arranged adjacent the teeth and'in lengthcoextensive with the guard, means for positioning the blade with itsedge adjacent the guard, and means for drawing the plate dge partprovided with guard.

toward the guard to deflect the guard teeth 40 outward relative to theblade.

6. In a safety razor, the combination with a blade holding plate and ayielding guard having its toothed edge arranged adjacent the edge of theholding plate and inclined outwardly, of means for causing the toothed[edge of the guard andthe plate to approach each other, whereby the]guard teeth are adjusted outwardly relative to the edge of the plate. Y

7. In a safety razor, the combination with a' blade holding plate, of ablade held'thereagainst, a guard having a yielding toothed edge portionarranged at an outward in-- clination to engage the blade, and means fordrawing the guard onto the blade'to force the guard teeth outwardlyrelative to the v cutting edge of the blade.

, 8. In a safety razor, the combination with a yielding guard memberbent at an out-' wardly extending angle having a toothedj edge portionadapted to move outwardly,

upon pressure being applied thereto, of a ade supporting plate memberoverlying the guard member, a blade supported by the plate memberinterposed between the same and the guard, and means for moving theblade and its supporting plate to force the "guard teeth outwardlyrelative to the cut'-' ting edge of the blade.

In testimony whereof, I have hereunto set my hand in the presence of twosubscribing witnesses.
